A method of controlling an aerosol-generating system, and the associated system, are provided. The system includes an aerosol-generating article and an aerosol-generating device having a detector configured to detect the presence of the article and to distinguish the article from other articles configured for use with the system, based on a spectroscopic signature of a taggant incorporated within a material of the article. The method includes detecting the presence of the article; determining whether the article includes a taggant; comparing the spectroscopic signature of the detected taggant with a look-up table of taggant spectroscopic signatures corresponding to articles configured for use with the system; preventing activation of the device, including preventing the supply of power to a heating element unless the detected taggant spectroscopic signature corresponds to an article configured for use with the system; and activating the device if the detected signature corresponds to the article.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of controlling an aerosol-generating system according to claim 1, further comprising detecting a presence of the aerosol-generating article presented externally to the aerosol-generating device.
3. The method of controlling an aerosol-generating system according to claim 2, wherein the preventing activation of the aerosol-generating device further includes preventing the aerosol-generating article from being received in the cavity of the aerosol-generating device.
6. The method of controlling an aerosol-generating system according to claim 1, further comprising increasing the temperature of the at least one heating element to above a temperature at which the taggant is deactivated, preventing the aerosol-generating article from being used again.
7. The method of controlling an aerosol-generating system according to claim 6, further comprising detecting an end of life of the aerosol-generating article, and increasing the temperature in dependence on the aerosol-generating article having reached the end of life.
9. The method of controlling an aerosol-generating system according to claim 8, wherein, in the first mode, the method further comprises detecting the presence of the aerosol-generating article using a proximity sensor, and in the second mode, the method further comprises determining the spectroscopic signature of the detected taggant using a light emitter and receiver.
